| 摘 要： | FLAC强度折减法将强大的数值计算能力与强度折减技术进行结合来描绘边坡的失稳形态及受力状态,判定边坡的稳定性。文中利用FLAC强度折减法对西南糯扎渡电站尾水出口边坡的稳定性进行分析,结果表明:强度折减所确定的边坡安全系数与极限平衡最危险滑面搜索所得的结果十分接近,滑面的形状及位置也很相似。

| Abstract: | FLAC strength reduction method combines strong numerical calculation ability and strength reduction technology to describe the destabilizing form and stressed condition of side slope so as to determine the stability of side slope.This paper carries out analysis on the stability of side slope at tail water exit of Nuozhadu Power Station in southwest region with FLAC strength reduction method.The result indicates that slope safety factor determined by strength reduction method is very close to the result thro... |
